STONE AND STUMP REMOVING MACHINE.

Specification of Letters Patent.

Patented Sept. 28, 1909.

Application filed September 4, 1908. Serial No. 451,694.

T 0 all whom it may concern:

Be it known that. I, AROHELAS VILLE- NEUVE, subject of the King of GreatBritain, and citizen of Canada, residing at Concord, in the county ofMerrimack and State of New Hampshire, have invented certain new anduseful Improvements in Stone I and Stump Removing Machines, of which thefollowing is a'specification.

My invention relates to stone and stump removing machines, andparticularly to a machine adapted to raise and move a stone or stump toone side at the same time, and to automatically release and drop thesame at the limit of the sidewise movement.

In the accompanying drawings, which illustrate my invention, and form apart of this specification, and wherein like characters are used todesignate like parts throughout the several figures, Figure l is a sideelevation of my improved machine. Fig. 2 is a rear elevation thereof.Fig. 3 is a top plan view thereof. Fig. 4 is a longitudinal sectionalview taken through the transverse tracks thereof. Fig. 5 is a plan viewof the upper track detached. Fig. 6 is a transverse sectional view takenthrough the tracks on the line 66 of Fig. 4. Fig. 7 is a similar view,on an enlarged scale, taken through the upper track on the line 77 ofFig. 5. Fig. 8 is a fragmentary horizontal sectional view taken throughthe upper track, and the automatic locking block thereof. Fig. 9 is afragmentary detail elevation of the support ing chair latch, and, Fig.10 is a similar view of the locking block release lever.

In the practical'embodiment of my invention, I provide a machineembodying frontand rear wheeled trucks 1 and 2, supporting an elevatedbody 3, composed of spaced horizontal beams, by means of diagonal beamsat and 5 respectively, extending upwardly therefrom and connected tosaid body 3. The rear truck 2 also supports a platform 6.

Mounted transversely of, and secured to, the body 3, respectively aboveand below the same, are the guide ways or tracks 7 and 8, the uppertrack 7 comprising a pair of spaced rails 9, secured by transverse upperstrips 10, and provided at one end with a stationary block 11, having aseries of transversely journaled pulleys 12. The rails 9 are alsoprovided with central longitudinal slots 14 to receive projectionsextending from sliding blocks 15 and 15, the former of which I term themovable pulley block, and the latter of which I term the locking andunlocking block. The movable pulley block 15 is provided with a seriesof pulleys 16 similar to the pulleys 12 of the stationary block 11, andconnected therewith by a rope 17 trained over the same and provided withone end secured to said block 11 at 110, and its other end extendingrearwardly of the device, about a pulley 18 journaled upon one of thetransverse strips 10. The locking and unlocking block 15 is mounted toslide between the stationary and movable blocks 11 and 15, and towardthe movable block 15 under actuation of a rope 19 secured at one endthereto and extending about the pulley 20 and rearwardly about a pulley20 journaled upon one of the transverse strips 10 at the opposite end oftrack 7, to the stationary block 11.

The lower track 8 comprises side rails 21, and is provided with uppertransversely journaled rollers 22 and 23 at the ends thereof, over whichoperating chains 24 and 25 pass, and are secured to the movable block15, and the locking and unlocking block 15 respectively. The chain 25,connected at one end as just described, to the locking and unlockingblock 15, is connected at its other end to a hook 26, swingingly mountedupon a bracket 28, provided with upper pairs of rollers 29 mounted tomove upon longitudinal inwardly extending ledges 29 of the side rails ofthe lower track 8, upon the movement of said locking and unlockingblock. The other chain 24L, connected at one end to the movable block15, and passing over roller 22, is projected through the rolling bracket28, and over the roller 27 thereof, and is provided upon its free lowerend with suitable grappling devices for engaging a stump or stone A,shown in Fig. 1, to raise the same.

In the position shown in Fig. 4, the stone or stump has been releasedafter being raised and shifted to one side of its original position.Thus, it will be apparent that in order to raise another stone or stumpand after the machine has been moved centrally thereover, the lockingand unlocking block 15 is moved toward the movable block 15, by pullingupon rope 19 until the same becomes locked at a position adjacent saidmovable block 14, when the roller mounted bracket 28 will be moved to aposition approximately centrally of the lower bracket 8 and alined abovethe stump or stone to be moved. The grappling devices at the lower endof the chain 24, are then secured in their engagement with the stump orstone, after which the rope 17 is pulled, causing the block 15 to movetoward the locking and unlocking block 15, at the same time pulling thestone or stump upwardly and sliding bracket 28 toward the end of thelower bracket 8, provided with roller 22. In its movement, the movableblock 15 contacts with and is locked into engagement with the lockingand unlocking block 15, traveling with the same in the direction of thestationary block 11, until the said locking and unlocking block is inthe position shown in Fig. 4, when it is automatically unlocked fromsaid movable block 14, the rope 17 of which is released at the sametime, to allow the weight of the stone or stump to draw the said movableblock 15 rearwardly to the position shown in Fig. 4, in which position,the said stone or stump will rest upon the ground at a point removedfrom its original position.

The locking and unlocking block 15 comprises a hollow body arranged withits direction of greatest length extending transversely between the saidrails 9 of the track 7, and provided at its ends with flanges 30extending into the longitudinal slots thereof, which slots have alinedpairs of openings 31 and 32, extending therefrom and transverselythrough the said rails 9, respectively adjacent the stationary block 11,and adjacent the pulley 20 about which the locking and unlocking blockactuating rope 19, passes. The hollow body of the block 15 is providedwith openings leading through the end walls thereof, and with a singlecentral opening 33 in its inner side wall. Mounted within the end wallopening, to be projected against the inner surfaces of the longitudinalslots of rails 9, are a pair of longitudinal movable locking members 34,terminating at their inner ends, adjacent the inner end of the side bodyopening 33, and pressed longitudinally outwardly by means of bell cranklevers 35, mounted within the body of block 15 and engaging portions ofsaid members 34, said bell crank levers being actuated by coil springs36. Thus, the outer ends of the locking members 34 are pressed outwardlyinto engagement with the inner surface of the longitudinal slots ofrails 9, and by the same means, will be projected within the alinedpairs of slots 31 and 32 when the same is moved into alinementtherewith.

The movable block 15 is provided with a projecting stem 37, extendingwithin and between the said rails 9, and toward the locking andunlocking block 15, and provided with an enlarged head 38, adapted to beprojected within the body side opening 33, and to pass between the innerends of the locking members 34, when the same are projected outwardlywithin either of the alined pairs of rail openings 31 and 32. Thus, whenthe block 15 is in the position shown in Fig. 4, and it is desired tomove the same toward the movable block 15, in order to project theroller bracket 28 centrally of its track 8, it is necessary to firstrelease the locking members 34 from their engagement within the alinedopenings 31 with which they would be engaged in such position. For thispurpose, I provide vertical rods 39 and 40 ournaled through brackets 41,upon the outer set of rails 9 adjacent the openings 31,'and providedwith upper and lower horizontal extensions 42 and 43, which lowerextensions 43 are provided with angular ends 44, projecting within saidopenings 31, to abut the ends of the locking members 34 of block 15,when the same are projected therein, whereby the said locking members 34may be forced inwardly within block 15,

when said rods 39 and 40' are rotated in their journals.

A rope 45, having its end secured to the apertured end of the upperhorizontal extension of rod 40 and extending about a. roller 46journaled at the end of the upper horizontal extension of rod 39, istrained over rollers 47 and 48, ournaled upon one of the side rails 9,and serves to swing said upper horizontal extensions 42 inwardly towardone another, thus rotating the rods 39 and 40 to release the block 15,as just described. In its movement, toward the movable block 15, thelocking and unlocking block 15, will of course, become locked inalinement with the pair of openings 32, by engagement of its springactuated members 34 therein. Thus, upon the movement of the movableblock 15 toward said block 15, its headed stem 37 is permitted to passwithin the body side opening 33, between the inner ends of the lockingmembers 34, until its head 38 presses against the ends of the bell cranklevers 35, in opposition to the actuating springs 36 thereof, wherebythe said levers will be rocked upon their pivots to draw the lockingmembers 34 inwardly from the openings 32 and the said block 15 will thenbe free to move with said block15, until said block 15 reaches theopenings 31, and the block 15 will be released therefrom, as beforedescribed.

The rope 45 operating the releasing members 39 and 40 of block 15,extends down-. wardly upon the diagonal frame beams 5, and beneath aroller 49, journaled uponone of said beams, and is connected at its endto the apertured end of a rocking foot lever 50,

mounted upon the platform 6, and shown particularly in Fig. 10. Pressureupon said foot lever thus releases block 15 from its position shown inFigs. 4:, 5 and 7. The actuating rope 17 of blocks 15 and 15respectively, extends downwardly between the diagonal frame beams 5, andare connected to an anchor plate 51 and a frame 52 respectively, saidframe 52 being operated by a handle 53, to draw block 15 along track 7as shown in Figs. 2 and 3. Rotatably mounted upon and extending upwardlyfrom the platform 6 is a derrick pole 54, provided with a boom 55swingingly connected thereto at its inner end, and having a block andtackle connection 56 at the upper end thereof, with the outer end ofsaid boom 55 to raise and lower the same, which block and tacklearrangement has its actuating rope 57 extending downwardly beneath aroller 58 journaled upon one of the diagonal frame beams 5 and adaptedto be secured to an anchor plate 59. The pulley or upright 54 may berotated, and the boom 55 thereby swung in either direction by ropes 60connected at their outer ends adjacent the outer end of said boom, whichropes pass through hoops 61, extending upwardly from the upper track 7adjacent each end thereof, and are adapted to be secured at their otherends to anchor plates 62. The boom 55 carries upon its outer end, asupporting frame 63, adapted to be lowered to rest upon the ground at anangular position with relation to the body of the machine, as shown inFig. 3. The boom 55 and the pulley or upright 54 are provided withrollers 64: and 65 respectively from which a chain 66 extends, and isadapted to be secured at its free end beyond the boom roller 6 1, to ahook 67 carried by the end of the lower track 8 to which the stone orstump A travels before it is released, thus preventing the overturningof the machine. The opposite end of chain 66 beyond the pulley rollers65, is secured to a ratchet lever 68, shown in Fig. 9, which ratchetlever is pivotally mounted upon the pulley or upright 54, and iscontrolled by a relatively engaging pawl 69 to maintain the said chain66, taut.

From the foregoing description, the operation of my improved machine, itis thought, is to be perfectly understood, although it will be well tostate that the side support for the same is provided in the form of aderrick in order that such support may be raised and swung upon andabove the main frame when the machine is being transported from place toplace.
